DESCRIPTION
The IS725 is an optically coupled isolator
consisting of infrared light emitting diode and a
high voltage NPN silicon photo darlington which
has an integral base-emitter resistor to optimise
switching speed and elevated temperature
characteristics in a standard 6pin dual in line
plastic package.
